DuMont K1436P10 4" Dark Trace Storage Tube “Skiatron”
Tube cathodique à trace sombre

Instead of the usual phosphor screen, this tube uses a screen of potassium chloride, which is a material known as a scotophor or cathodochromic phosphor. Wherever struck by an electron beam, the normally white screen turns magenta. This coloration remains until erased by infrared radiation.

The tube was designed with a spherical faceplate for use in the optical system of projection radar displays. Drawbacks included relatively long infrared erasure times (greater than one second), low contrast and low sensitivity.
